Application led December 28, A19,252. Serial No. 609,380.

This inventionl relates to improvements in water heaters. y f l One object ofthe invention is to provide an efiicient'` hot. water heater, of simple construction, comprisinga lire pot, forming the heater proper, and a"` water storage tank connected thereto, together with means `for effecting proper circulation of` the water in' and between the fire pot and thetank.`

Another object of the invention isto pro-` the fire pot, formingthe heater proper, and the storage tank are separate, detachably Connected units, one size y being adapted to have assembled `therewith any one of `a number of diierent `sizes of water storage tanks, whereby` thediferent sizes ofcommercial tanks, of this type, may be made use of. T

Anotherobject of the invention is to provide a hot water heaterof the type specified, wherein the fire pot is water jacketed to form the `heater proper, thewater storage tank 'is supported by the lire pot in such a man` 11er that the bottom thereof is exposed to the heat of the fire within the -fire pot,`and `separable pipe connections are provided between the storage tank andthe fire pot to detachably connect the :same and.. establish communication therebetween foi-the proper circulation of the water.` f i In the drawing formi s eciication, Fig. 1 is a central, `vertical. sec,

tional view taken through a waterheater, `1

showing my `improvements in` connection therewith.. YFigi `2 is a `horizonte-1,. transverse sectionalyviewtaken substantially on theline .2-1--2` `of Fig. 1.` And Eig.- 3 is wa horizontaltransverse sectional `view taken substantially on the` line 3 3 of Fig. 1.

" As shown in said drawing myimproved f water heater comprises broadly, acylindrical supporting member VA, a

Abase casting or water jacketed fire pot B, a cylindr1cal `storage tank C and water conducting pipes D and E.

The supporting member A `comprises af hollow frusta-conical casting which supports `the grate member 10f and is provided with a `thereof for Athe removalofthe ashes.

The `fire pot B base casting A. Said fire pot B `is provided with a water compartment defined by an outer cylindrical wall 12, a `lower inner cylindrical wall"1v3, an upper narrow cylin-1` of re pot unit` ng apart; of this- "lthereinto a'nipp fthe fire potB is with a water inlet opening 24. `An Aintexrorly screw-threaded pipe flange member ,25,

the opening y opposite ends by a door 11 to provide `access to theinterior is directly supported by the.`

drical Wall 14 and top and bottom annular walls 1114 and 115. Near the` top, the fire pot B` is'provided with a hollow :horizontally extending water partition 15 having top and bottom horizontally extending walls 16 and 17 ,said partition being in communifcationwith the other `portions ofthe water chambered re pot. Preferably, a plurality of arches 116 are employed on the underside' of` the wall 16 to .thereby provide a greater amount `ofrdirect heating surface. By referring to Fig. 3, it will be noted that two circular lues 117 are provided within the hollow partition, said iues 117` being located to one side and relatively closely adjacent the pipe D, `for the purpose hereinafter specified. y y y At the front side of the lire pot are provided doors 18`and 19. The door 18 closes an opening through the front wall of the fire pot which leads to the combustion cham ber. The door 19closes an opening leading `to the flue chamber for a purpose herein-` after described. Diametrically opposite to the door" 19, the fire pot casting is provided with an opening 20, communicatin with the flue box. A` fitting 21 is, suitab y secured` to `the outer wallA 12 ofthe lire pot B in alinement `With thefopening 20 and `serves n as a connecting means for an ordinary stove pipe, through whichthe `gases of combustion `aregcarried off.` 'The upper wall 16 `or'ypthe `partition 15,A is` prbvided with a` Y screw threaded openin 22 adaptedto have screwed e 23. `The outerwall 12 of provided nearV its lower enjd issecured to the wal1'12` in alinement with 24 and has screwed therein a nipple 26. .f y

lTo promote economy in iirstcoist and-alsol i to minimize the expense of settin up the heater,1 preferably employ tanks o well known commercial `form such as now used for heating water for household purposes.

Thetank C `as shown in the drawin s, comprises a cylindrical shell 27close at `its substantially convex top wall` 28 and an inset, dished bottomwall 29.

`The upper wail 28 of the tank C is provided with the usual hot water outlet opening 30,

`having `associated therewith the internally sscrew threaded ,pipe` `zfiange member 31,

`adaptedto have` screwed thereinithe outlet los pipe 62.-` Near the lower endof the storage i i nected to the lower end of the tank-C, the shell 2T is provided with an opening 33, having associated therewith an internally screw threaded pipe flange mein# bei' 34, receiving the'nipple 35. The bottom wall 29, of the storage tank C is provided with an opening 36. A flanged collar 37 eX- tends within theopening 3G and is suitably secured to the bott-oni 29 ot the tank. The opening 38 of the `flanged collar 37 is oi? such a sine as to freely receive the .pipe D. As clearly shown in Figures 1 and 3, a. pipe D is located tol one sine ot the heater and at a point midway between the tlues 117, for the purpose hereinafter nescribed.

The pipe D passesthrough the opening 38 andv held in lined position therein by the nut 39 threaded within the opening 38 of the collar 36. Suitable packing is inserted between the internal flange 40 of the collar 35 and the nut 39 to properly seal the opening and prevent leakage ot water between the pipe and the collar. rlhe pipe D extends upwardly internally of the tank to within a short distance of the top thereot. The nipple 22, connected to the upper wall of the partition 17 of the lire pot is detachably conpipe D by a union 41.

The pipe E compri-ses a T 42 connected at one end to the nipple 26 and connected at the other end to a cold water supply pipe 43, a relatively short length ot pipe 44, connected to the side opening oi' the T, a union 45, a relatively long pipe 46, and an i. 47 connected to the nipple In the operationv of `my improved water heater, the water contained within the water jacket of the tire pot being exposed to the direct heat of the fuel in the vcombustion chamber, is raised to a higher than the water contained in the storagetank C Vand rises upwardlythrough the pipevD and is directed by ythe latter to the upper end oit' said'tank. Circulation between the tank C and the water jacket of the tire pot B is provided by the cooler water settling to the bottom of the tank C, and passing through the pipe E to the bottom ot the water jacket of the lire pot Bu rlhe path oit' circulation ot the water is clearly indicated by the arrows inv Fig. 1. The cold water is fed to the water heater through the supply pipe 43 passing into the lower end of the water jacket of the tire pot B, and the heater water is drawn od through the usual outlet pipe 32.

As will be evident from the preceding description considered in connection with thel drawing, the products of combustion will travel first along the under side of the hor-V izontal partition of the lire. pot toward the flue openings 117, thence upwardly through the latter immediately around the lower end of the pipe 4D, and thence will travel horizontally in the reverse direction or temperaturerand capacities, Ithus further toward the lett as viewed in Fig. 1, thus providing direct Contact with the bottom wall 29 of the tank and making the latter a direct heating surface. tion linally pass out through the :[iue pipe 21 The products of combus` to the chimney.` By this arrangement, l ob- Y tain, for a heater o1" given size, maximum direct heating surface.including the bottoni walllof the tank; also products ot combustion when at their highest temperature arecon-V centrated about and against the lower end of the pipe Dso as to 'raise` the temperature oglj the water at the bottom :ot the kpipe D very rapidly vand `ettect extremely rapid circulation ot the water upwardly through the pipe D and thence around witliinthe tank C.' t

Due to ythe' concentrationxof the heat, vas

aforesaid, at the lower end of the pipe D y the union 41 for assembling andV disassemcling the parts, is greatly facilitated since ample room is provided for applying the wrench to the union and for oscillating the .handle within the door onenine.

By making the upper wall 114 ofthe ltire poty oi' appreciable width, asheretotore described andas shown in the drawing, I am enabled toY utilize a tire pot of'one size with commercial storage tanks of ditferent diameters as well as tanks of different heights decreasing the cost ofmanufactiire.
